Flow simulation in a flip bucket spillway: Dakpokei reservoir case study

Tạp chí Khoa học và Công nghệ
Simulating the hydraulic behavior of an ogee spillway with a free jet energy dissipation form is a complex task due to the involvement of two phases: liquid (water) and gas (air).

Optimisation of Stilling Basin for an Ogee Spillway for Enhanced Energy Dissipation

Spillways are meant for disposing of the excess flood safely to the downstream without causing any damage to its upstream, the structure itself and its downstream. Energy dissipator is essential component of spillway which dissipates the incoming excess energy. The most common energy dissipators are ski jump buckets, roller buckets, hydraulic jump type

Physical and Numerical Comparison of Flow over Ogee Spillway in the Presence of Tailwater

Journal of Hydraulic Engineering, 2006
Data obtained from two physical models were compared to the results obtained from numerical model investigations of two ogee-crested spillways. In 2001, Savage and Johnson investigated ogee-crested spillways without the effect of tailwater; the present study includes the influence of tailwater on the spillway.

Prediction of cavitation damage using SVM model based on air–water two-phase flow over dam spillway

Applied Water Science
Cavitation is one of the primary causes of breakdown and failure on chute spillways, causing surface damage and structural destruction. In this research, a three-dimensional two-phase flow over an ogee spillway was modeled using the FLOW-3D model for the

Evaluation of scale effects in physical modeling of combined ogee and sharp-crested weir flow using a 3D CFD model

Water Science and Engineering
Research on scale effects on flows over weirs has been conducted on a limited basis, primarily focusing on flows upstream of a single-type weir, such as ogee, broad-crested, and sharp-crested (linear and non-linear) weirs.
